Well if by meditation we are talking about some sort of samadhi-state couldn't you class the person deeply enthralled by video games as being in a working samadhi state? Not the same as absolute samadhi by any means.
I don't have much experience with this while sitting, but I have felt a force like this in a similar manner, mostly spontaneously while practicing (sober) mindfulness in a variety of contexts.
It seems like kundalini yoga is the discipline you want to research if you're interested in trying to harness and focus this energy, which in that tradition is conceived of as a coiled serpent of libidinal energy that rests dormant at the base of the spine, and which can be awakened and directed through the chakras into the head.

That all aside, i agree 100% with CoffeeDrinker, that being sober and meditating will get you the most out of the experience in my opinion.
Not to mention the most out of the drug experience too. Psychedelics go best with sensory stimulation, of the positive variety at all times.
